With two of Oklahoma State's backup cornerbacks out with injuries, starters A.J. Green and Rodarius Williams bore much of the load in the Cowboys' season-opening victory Thursday.
OSU won comfortably without Lamarcus Morton and Tanner McCalister, defeating Missouri State 58-17, but the position could prove a point of concern the closer the Cowboys are to Big 12 play.
Morton is listed as Williams' backup on OSU's depth chart for Saturday's game against South Alabama, and although McCalister isn't listed, coach Mike Gundy said he could return from a thumb injury in time for this weekend.
